This project addressed the construction of channels with slopes greater than 80°, a condition that represented high levels of complexity for traditional solutions, mainly due to uncontrolled concrete consumption and difficulty in execution.

Faced with this scenario, the use of geocells was chosen, which allowed for significantly faster progress compared to reinforcing and installing rebar. Furthermore, the shotcrete placement for a channel achieved uniform pouring and reduced construction time, thus optimizing construction efficiency in a highly technical environment.

Given the anticipated increase in the flow of the Sechín (Casma) and Huarmey Rivers, authorities, managers, contractors, and suppliers promoted the construction of riverside defenses to control erosion, protect bridge abutments, and mitigate the risk of flooding in vulnerable areas.

To this end, geocells filled with crushed stone were used, an innovative solution specifically designed to withstand high drag velocities. This technology was implemented on longitudinal levees, the most affected by previous hydrometeorological phenomena, ensuring greater structural stability in the face of extreme events.

Faced with the threat of the El Niño phenomenon and the potential flooding of the Zarumilla River, the Authority for Reconstruction with Changes, in coordination with the project contractor, continued the construction of riverside defenses along an 11.75 km stretch along the left bank of the river, between the districts of Matapalos and Papayal, in the province of Zarumilla, Tumbes. The project location presented a severe shortage of rock material, making a rockfill-based solution unviable due to the high costs and time associated with extracting, processing, and transporting rock from remote quarries.

Faced with these technical and economic challenges, Grupo TDM proposed a more efficient riparian defense system using geosynthetics. This enabled the lining of 9,987 meters of levees with geocells and concrete and the protection of an additional 2,010 meters with anti-scour Hydrobags. This solution not only met the demanding engineering criteria developed over more than six months, but also guaranteed efficient execution with high quality standards, benefiting more than 2,600 residents, 620 hectares of agricultural crops, and reinforcing the safety of the entire area against extreme events.

The project in the Corrales stream was part of the comprehensive solution for the Tumbes River, aimed at directly protecting the residents of the El Triunfo, Buena Vista Baja, Los Ángeles de Corrales, Agel Josué 2012, Barrio Nuevo, and Palmeras neighborhoods, as well as the entire population of the district.

Operations began with dredging, followed by slope lining using geocells and concrete, applied to longitudinal dikes that are key to the area’s water security. This intervention was essential for strengthening the protection of surrounding communities from flood events, significantly contributing to the country’s security.
